The string, delimited by quotes or apostrophes, is scanned for a substring which selects which instruction set is used. When the program is invoked, this operation is performed on the name of the program, then the -p optional arguement, if any, and then any CPU statements. The last one selects which subset of the instructions the assembler will accept. The instruction set can be changed at any place in the source file.
